I consider STS 2.0 Cathe's BEST strength series to date. I absolutely loved it...I thought there would be way too much downtime between sets but the pacing is perfect and I liked it much better than the original STS.
The total body workouts were my favorite (found some GREAT premixes too), followed by the Body Parts and the Upper/Lower Splits. I liked the LB workouts much better than the UB workouts.
The standing abs workouts were really great warm ups done before the strength workouts which worked well for me to get in abs before so I wasn't dreading them as add-ons after the main workout.
Her Mobility workouts were very good but I didn't care much for the stretches/yoga, which I surmised since I'm not a fan of Cathe's yoga. I added on a 10-15 min. Mady Morrison stretch after the workouts often which stretched me out more for my present issues.
I loosely followed Cathe's LIS/STS 2.0 rotation but replaced the LIS workouts with my speed walks usually done 3x/week and added in various other mobility and yoga add-ons which helped balance everything out too. (And I need to note I'm sure I wouldn't have received such good results without including some type of cardio--my body demands it)!
I got noticeably stronger and shaved off some inches, mostly in the LB, but that may have been reflected from my walks also. I should note here too that I used my Weider machine (incorporating pull downs) very regularly with this series which helped with my strength gains as well. However, I feel like I may need to do more for my upper body to gain more definition, but it's tough to go so heavy with wrist/shoulder issues!
Thankfully, my 2# wrist weights were staples in my workouts to take it up just 2# where I could!
I think it's the combination of weights and bands and recovery that make this series so awesome to keep the muscles guessing and balanced. I really didn't get that dread factor at all since there is so much variety in the series. By the end of the 12 weeks, though, I was ready to move on to something and someone else.
Great series and highly recommend!
